The understanding of spectra of detected gamma rays is necessary for developing models for acceleration, emission, absorption and propagation of very high-energy particles at their sources and in space. After the end of EGRET on board the Compton Gamma Ray Observatory this energy region is not covered by any other experiment, at least up to 50 GeV where ground Cerenkov telescopes are beginning to take data. Here we will review the status of the space experiments that will fill this energy region: AGILE and GLAST, with particular emphasis at the connection with all the other ground planned experiments and at the contribution of these experiments to particle physics.","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116099300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, but with an increasing rate, innumerable articles were steadily produced on the subject by theorists and phenomenologists, and almost as many and often redundant papers have been reviewing them. There is no doubt that the end of the cosmic-ray energy spectrum triggers an uncommon excitation in several communities: astrophysicists, cosmologists, and particle physicists, generating fruitful overlaps in their works. One may consider that it was not quite useful to add one more review to the existing list. However, it seems to us that the presently available (although scarce) experimental data were not fully used in the past for a serious evaluation of many proposed models. In parallel, new ideas are also being considered by the experimental groups preparing the next generation of experiments in the field, and some decisiv...","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115261929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

His obvious gift of ubiquity both in physics and in the organization of meetings led a number of us to suspect he might make a secret use of extra dimensions. In this exotic world, we explore how neutrinos might disappear and re-appear, and how the triplication of generations could occur. We study four-dimensional flavor neutrinos coupled to a single “bulk” state, i.e. a Kaluza-Klein tower induced by a fifth dimension. We put special emphasis on understanding the spatial development of the neutrino disappearance, the possibility of resurgence and the effective flavor transitions induced in this mechanism. The first part of this talk concentrates on neutrinos, and makes ample reference to the presentation of Y. Suzuki. In the second part, we will deal with the somewhat unrelated possibility of obtaining three generations of particles in four dimensions from only one, vector like family in six.","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115784912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basis for this statement is the theorem about a non-renor-malization of induced charge provided that expansion in momenta of background fields is valid. In the examples presented in this talk we demonstrate that induced charge matching conditions are generally not equivalent to ‘t Hooft anomaly matching conditions. In particular, the corresponding constraints in softly broken supersymmetric QCD suggest non-trivial low energy mass pattern, in full accord with the results of direct analyses.","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115388863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
